4 Claims.

This invention relates to holders for hollow cones, or other hollow or tubular cores holding yarn or thread to be unwound in creels or other supports used with or in winding machines, such as cop-winding, warping machines, knitting machines or weaving looms.

More particularly this invention relates to holders on which wound packages of heavy, strong yarn are held securely in place, the yarn being wound at a very high speed on beams.

For simplicity herein, core is meant to include any hollow body for carrying wound thereon, yarn, thread, or the like, whether cylindrical, conical or the like. Yarn is intended to include threads, strands, cords, or other filamentary material whether it is plied, twisted, or untwisted.

Many holders in the prior art had the disadvantage that when the yarn or thread snagged 4 during unwinding from the yarn core, the yarn had a tendency to pull the core oif the yarn holder.

The main object of the present invention is to provide a simple and efficient holder for a hollow core carrying wound yarn or thread thereon securely in any position and to provide a simple and eflicient means to mount and dismount the core on the holder.

Other objects and advantages of the present invention will become apparent by a study of the accompanying drawings and the following description thereof.

In the drawings- Figure 1 is a side view of a preferred embodiment of the holder and spindle,

Figure 2 is a sectional view taken along section lines IIII of Figure 1,

Figure 3 is a sectional view of the holder and spindle assembly along section lines III-III of Figure 2,

Figure 4 is a side view of the holder and spindle assembly with the core fixed thereon,

Figure 5 is a side view of a modification,

Figure 6 is a longitudinal sectional view of Figure 5, and

Figure 7 is a sectional view taken along section VII-VII of Figure 6.

As shown in Figures 1 to 4 and more speciflcally in Figure 3, reference character I indicates a yarn core holder in which a central bore 2 extends along the center line from the base of the holder. Spindle 3, which is mounted on a creel or other support (not shown) extends into the central bore 2, and carries the holder l, the holder being positioned thereon by means of the flange 4, integrally mounted on and concentric with the spindle 3. The holder I is securely held to the spindle 3 after positioning by the set screw 5.

The yarn core holder I has an eccentric flange or lip 6 integrally attached and extending perpendicularly to its central axis at its free end. Two springs I and 8 whose retaining grooves 9 (one of which is shown). are generally parallel to the generatrix of the yarn core holder I, extend from a suitable point behind the flange. Springs 1 and 8 are positioned radially in such a way as to be opposed to the flanged lip 6.

The springs I and 8 are arcuate so that when the core I I, on which the yarn I0 is wound, is slipped on the holder, they will exert a force internally against the core II, and hold the core securely against the surface of the holder extending from behind the flange 6. The diameter of the core II is such that its smallest end is equal tothe greatest diameter of the holder at its free end. In this way the cardboard core can easily be mounted and dismounted. The thickness of the core as shown by reference character I2 is such that it is greater than the distance the flange lip 6 overhangs the yarn cone holder at its smallest end. This is done so that no yarn will catch under the flange lip 6 and snag.

A modification of the present invention is illustrated in Figures 5 to '7. The yarn core holder is made in two parts, I3 and I4, which are segments of a circle with a segmental bore 23 similarly cut in each. The bore 23 is placed around the spindle with the bases of the yarn core holder segments I3 and I4 parallel. When they are so placed, any plane cut through the yarn core holder parallel to the base forms a circle. The yarn core holder is fastened together by a split resilient retaining ring l8, and

a spring adjustment screw 26. Rotary and longitudinal motion of the yarn core holder is restricted by a set screw I! in a circular groove I6 on the spindle IS. A segmental flange is mounted integrally on each of the segmental sections of the yarn core holder at their free ends.

When the yarn core is placed on the yarn core holder the smaller diameter of the said yarn core is held in place by the flange l9, which is forced over the outer circular edge of the yarn core by means of a spring 2|, loosely held on screw 2!! in recess 22. Any desired spring tension can be obtained by setting the screw 20 to any depth in the yarn core holder segment I 4. The yarn core holder segment I3 is recessed to receive screw 20, as is yarn core holder segment I 4, to

receive set screw H. In this way, no yarn can be snagged in any way in the unwinding process.

An empty yarn core is easily removed from a holder provided according to the invention, needing only to be lifted over the flanged end when the yarn core holder is squeezed together.

Although this invention has been described with reference to improvements shown, it will readily be appreciated that numerous changes may be made without departing from the spirit and scope of the invention as described in the appended claims.

We claim:

1. A yarn core holder having an external conical surface for receiving a yarn core, support means secured to and extending from the larger end of the holder, an eccentric flange at the 1111- supported end of the holder for normally preventing longitudinal movement with the yarn core relative to the holder, and resilient means in the surface of the holder on the side thereof opposite the flange for engaging the interior surface of the yarn core.

2. A yarn core holder having an external conical surface for receiving a yarn core, support means secured to and extending from the larger end of the holder, an eccentric flange at the unsupported end of the holder extending from the conical surface of the holder a distance less than the thickness of the core, and resilient means in the surface of the holder on the side thereof opposite the flange for engaging the interior surface of the yarn core.

3. A yarn core holder having an external conical surface of revolution for receiving the yarn core, support means attached to the larger end of the holder, a laterally extending eccentric flange at the unsupported end of the holder, the Width of said flange and the unsupported end of the holder being less than the smallest diameter of the core, at least one groove parallel to the generatrix of the surface of the holder extending within a portion of the surface radially opposite the surface from which the flange extends, and an arcuate spring supported within the groove hav- 4 ing an arcuate portion spaced between its ends projecting radially outwardly from the surface of the holder for engaging the exterior surface of the core.

4. A yarn core holder having an external conical surface of revolution for receiving the yarn core, support means secured to the larger end of the holder, an eccentric flange at the smaller end of the holder, said flange and the smaller end of the holder having a combined width less than the smallest diameter of the core, a pair of grooves parallel to the generatrix of the holder surface extending within a portion of the holder surface which is radially opposite the portion of its surface from which the flange extends, and a resilient means extending from each of the grooves radially outward from the adjacent holder surface for engaging the core.
